The most important objective in the present day studies of the passive suffrage is to identify the legal collisions and make proposals for filling in the legal gaps encountered by the law enforcers in the context of the tasks set forth before them, i.e. to ensure implementation of the passive suffrage of the candidates. Nowadays, the need to carry out the legal analysis of the impact imposed by the conceptual legislative innovations on using the right to passive suffrage has become evident. The aim of this paper is to analyse the existing restrictions of passive suffrage, as well as to study the eligibility and limits of these restrictions.Materials and Methods. In the article, the recently published works of native scientists, the mass media materials, federal legislation, decisions of the Constitutional Court of the Russian Federation in the studied area, the regulatory legal acts adopted by the Central Election Commission of the Russian Federation, as well as the results of the work of the election commissions have been analysed. The study was based on such commonly accepted methods of scientific cognition as the dialectical and dogmatic-legal methods, as well as the methods of analysis, synthesis, induction and deduction.Results. The issues of legitimacy of establishing the additional restrictions to the rights of citizens have been investigated. The conclusion has been made not only of great importance to protect the human rights and freedoms, but of urgent need to comply with the legal restrictions of these rights. The concepts of restrictions and violations of the human and civil rights and freedoms have been differentiated, and the statutory expression of the suffrage restrictions has been analysed.
